How to generate multiple ports with same wsdl in JAXWS

I have this WSDL:

<?xml version="1.0" encoding="UTF-8"?>
<wsdl:definitions
        targetNamespace="http://ift.tt/1B2MKN7"
        xmlns:tns="http://ift.tt/1B2MKN7"

                    </xsd:sequence>

            <!--<wsdl:output message="tns:endResponse"/>-->
        </wsdl:operation>
    </wsdl:portType>
    <wsdl:portType name="Process2PortTypeCallBack">
        <wsdl:operation name="end">

        </wsdl:operation>
    </wsdl:portType>
    <wsdl:binding name="process2Soap11" type="tns:Process2PortType">

            <wsdl:input name="startRequest">

            <soap:operation soapAction="end"/>
            <wsdl:input name="endResponse">

            </wsdl:input>
        </wsdl:operation>
    </wsdl:binding>
    <wsdl:service name="process">
        <wsdl:port name="processSoap" binding="tns:process2Soap11">
            <soap:address location="http://localhost/sample"/>
        </wsdl:port>
        <wsdl:port name="processSoapCallback" binding="tns:process2CallBack">
            <soap:address location="http://localhost/sampleCallback"/>
        </wsdl:port>
    </wsdl:service>
</wsdl:definitions>

I am trying to create a service implementation using Apache CXF with JAXWS endpoints and Spring, I know how to create an endpoint for each port, using something like this in the Spring context file:

<jaxws:endpoint id="personEndpoint1"
                implementor="#process"
                serviceName="hello1"
                endpointName="a"
                address="/process">

    <jaxws:properties>
        <entry key="schema-validation-enabled" value="true"/>
    </jaxws:properties>
</jaxws:endpoint>
<jaxws:endpoint id="personEndpoint2"
                implementor="#processCallback"
                serviceName="hello1"
                endpointName="a"
                address="/process2">

    <jaxws:properties>
        <entry key="schema-validation-enabled" value="true"/>
    </jaxws:properties>
</jaxws:endpoint>

However, this solution creates two endpoints with different WSDL urls:

. http://localhost:8080/process?wsdl

<?xml version="1.0" encoding="UTF-8"?>
<wsdl:definitions xmlns:xsd="http://ift.tt/tphNwY" xmlns:wsdl="http://ift.tt/LcBaVt" xmlns:tns="http://ift.tt/GArMu6" xmlns:soap="http://ift.tt/KIQHA2" xmlns:ns2="http://ift.tt/LcBaVu" xmlns:ns1="http://ift.tt/1B2MKN7" name="hello1" targetNamespace="http://ift.tt/GArMu6">
    <wsdl:import location="http://localhost:8080/process?wsdl=Process2PortType.wsdl" namespace="http://ift.tt/1B2MKN7"/>
    <wsdl:binding name="hello1SoapBinding" type="ns1:Process2PortType">
        <soap:binding style="document" transport="http://ift.tt/LcBaVu"/>
        <wsdl:operation name="start">
            <soap:operation soapAction="startAction" style="document"/>
            <wsdl:input name="start">
                <soap:body use="literal"/>
            </wsdl:input>
        </wsdl:operation>
    </wsdl:binding>
    <wsdl:service name="hello1">
        <wsdl:port binding="tns:hello1SoapBinding" name="a">
            <soap:address location="http://localhost:8080/process"/>
        </wsdl:port>
    </wsdl:service>
</wsdl:definitions>

and

. http://localhost:8080/process2?wsdl

<?xml version="1.0" encoding="UTF-8"?>
<wsdl:definitions xmlns:xsd="http://ift.tt/tphNwY" xmlns:wsdl="http://ift.tt/LcBaVt" xmlns:tns="http://ift.tt/GArMu6" xmlns:soap="http://ift.tt/KIQHA2" xmlns:ns2="http://ift.tt/LcBaVu" xmlns:ns1="http://ift.tt/1B2MKN7" name="hello1" targetNamespace="http://ift.tt/GArMu6">
    <wsdl:import location="http://localhost:8080/process2?wsdl=Process2PortTypeCallBack.wsdl" namespace="http://ift.tt/1B2MKN7"/>
    <wsdl:binding name="hello1SoapBinding" type="ns1:Process2PortTypeCallBack">
        <soap:binding style="document" transport="http://ift.tt/LcBaVu"/>
        <wsdl:operation name="end">
            <soap:operation soapAction="end" style="document"/>
            <wsdl:input name="end">
                <soap:body use="literal"/>
            </wsdl:input>
        </wsdl:operation>
    </wsdl:binding>
    <wsdl:service name="hello1">
        <wsdl:port binding="tns:hello1SoapBinding" name="a">
            <soap:address location="http://localhost:8080/process2"/>
        </wsdl:port>
    </wsdl:service>
</wsdl:definitions>

This is not what I need, I need that the two ports are available using the same WSDL address, as in the original WSDL. How can I achieve this using JAXWS and Spring configuration?
